Re: HP Officejet 6310 on Windows 7 shows up as offline. How do I get it back online?

I have tried the 1st set of steps below. "Use printer online" is not a visible option.

I also tried the 2nd set of steps below and that works...but my printer is still "offline".

I got into this stituation because I was getting a left cartridge error on my 6310 network printer. I got that fixed by pressing "6" and "#" simultaneously and then turning off and back on the printer.

My printer is connected via ethernet cable to a network router. All other Mac computers can still print to the 6310 across our home network. I am running Windows 7 64-bit pro on my PC and cannot print.

Any ideas? Oh ...and please don't recommend the HP diagnostic tool...as it doesn't provide any useful help for my situation.

Hopefully, one of you bright HP engineers can dissuade me from using my 6310 as my new boat anchor. )
